While high beginning-of-life efficiencies are important for space solar cells, the end-of-life performance is also critical factor. Two different prediction methods, "relative damage dose" and "displacement damage dose" methods, based on analysis of ground radiation test have been produced. We report proton radiation response for triple-junction space solar cells and analyze prediction methodology for the cell radiation response using the two methods. The results show that V
degradation behavior can be predicted by taking into account a cell structure and proton penetration depth. Accurate prediction of power degradation, however, is required to determine the current-limiting sub cell after proton irradiations.

Times Cited Count：2 Percentile：18.89(Chemistry, Physical)Four kinds of film dosimeters well-characterized for low LET radiations were applied to 3-45 MeV/u ions. The dose responses relative to those for low LET radiations are almost one up to about 10 MeV/(mg/cm
) and gradually become smaller with increase of the stopping power. Overall uncertainty in ion beam dosimetry using these characterized dosimeters is better than 
5%(1
) including uncertainty in fluence measurement(2%). Lateral and depth dose profile measurements were achievable using characterized Gafchromic dosimeters with the spatial resolution of better than 1 and 10 
m, respectively.
